In addition to the set-text you will need to examine the concept of Discovery in other texts. These have been called additional, related and supplementary texts/material. In the HSC paper they are referred to as 'texts of your own choosing'. The purpose of this is to allow you to:

(i) examine the concept in other texts by other composers

(ii) illustrate your understanding of the concept and how it is used by other composers

You will also have to have 'texts of your own choosing' for your Module C study.

There will be lists of related texts throughout the internet. The lists will be comprehensive and it will be up to you to decide which is the best option. When looking for additional material you are not limited to what you find on the internet lists. If you find something else you can use that.
